[Asterisk-Users] tieline digit timeout

[Tony]

I'm connecting to an NEC t1 card via t100p (working great so far!)
however I'm having problems dialing from the NEC system to an asterisk
extension (sip-grandstream). If I hit the trunck line and dial REAL
quick 103 I get the sip extension ringing; if I don't I get an invalad
selection message from asterisk - and I can see on the console only one
or two digits arrived.

How can I globally make asterisk wait for several seconds on that t100p?

Thanks,
